The electric telescopic rod 3 moves outward, driving the movable rod and the interactive screen 1 to move outward, and the interactive screen 1 moves to the outside of the driving slot 7 along with the movable rod, so that the teacher can observe the situation in the live broadcast room while writing on the blackboard.

[0030] The surface of the interactive screen 1 is provided with a dust blocking structure, which includes a shielding rod 9, a rotating rod 10, a folding film 11, a limiting groove 12 and a traction slope 13. The horizontal side of the shielding rod 9 is fixedly connected to the driving groove 7, and one end of the rotating rod 10 is rotatably connected to the driving groove 7 near the blackboard. The top of the rotating rod 10 is connected to the bottom of the shielding rod 9 through a folding film 11. The folding film 11 is transparent, foldable and dust-proof, and can be a transparent plastic film. The diameter of the rotating rod 10 gradually increases inward, the limiting groove 12 is opened at the inner top of the interactive screen 1, and the traction slope 13 is opened at the inner top of the interactive screen 1. The traction slope 13 is connected to the limiting groove 12, and one end of the traction slope 13 is located on the surface of the interactive screen 1. The folding film 11 is transparent, and when the rotating rod 10 rotates to the surface of the electric telescopic rod 3, the top of the rotating rod 10 fits with the connecting rod 8. When the interactive screen 1 moves outward, the limiting groove 12 moves outward, and the diameter of the rotating rod 10 in the limiting groove 12 gradually increases, causing it to be out of the limiting groove 12, so that the rotating rod 10 falls along the traction slope 13 when the interactive screen 1 moves outward, and the folding film 11 is unfolded to block dust.

[0031] One end of the rotating rod 10 is connected to a guide block 14, which is arc-shaped and tilted upward. A guide groove 15 is provided on the inner side of the driving plate 4. The guide groove 15 is a through groove, and a traction protrusion 16 is fixedly connected to the bottom of the guide groove 15. One end of the guide block 14 is located in the guide groove 15. When the electronic telescopic rod is retracted, the guide block 14 enters the guide groove 15, and the traction protrusion 16 drives the guide block 14 upward, and at the same time, the electric telescopic rod 3 drives the moving rod and the interactive screen 1 to retract into the driving groove 7.

[0032] A guide structure is provided on the side of the driving slot 7 close to the blackboard, and the guide structure includes a guide slider 20, a baffle 21, a connecting guide rod 22 and a guide arc 23. One side of the guide plate is fixedly connected to the inner side of the driving slot 7, one end of the guide slider 20 is in contact with the interactive screen 1, and the guide arc 23 is located on the side of the guide slider 20 away from the interactive screen 1. The baffle 21 is fixedly connected to the side of the driving slot 7 close to the blackboard through a bracket. The guide arc 23 and the surface of the baffle 21 form a guide space, and the two ends of the guide space are respectively connected to the traction slope 13 and the guide slot 15. A contraction structure is provided on the top of the baffle 21, and the contraction structure includes a plate body 24, a contraction slot 25, a spring and a contraction block 27. The contraction slot 25 is opened at the top of the plate body 24, and the bottom of the contraction block 27 is connected to the contraction slot 25 through a spring. A contraction structure is provided on the top of the baffle 21, and the contraction structure includes a plate body 24, a contraction slot 25, a spring and a contraction block 27. The contraction slot 25 is opened at the top of the plate body 24, and the bottom of the contraction block 27 is connected to the contraction slot 25 through a spring. After leaving the traction slope 13, the rotating rod 10 enters the guiding space, and enters the guiding groove 15 under the traction of the baffle 21 and the guiding slider 20, and the folding film 11 unfolds. During the unfolding process, the folding film 11 compresses the shrinking block 27 and the spring into the shrinking groove 25 to prevent the baffle 21 from blocking the folding film 11.

[0033] A collecting plate 28 is fixedly connected to the bottom of the baffle 21, and a collecting groove is provided on the side of the collecting plate 28 away from the baffle 21. A squeezing roller 29 and a fixed roller 30 are fixedly connected in the driving groove 7. The squeezing roller 29 and the fixed roller 30 are respectively located on both sides of the folding film 11. A spring groove is provided on the upper surface of the fixed roller 30, and a vibration block 31 is connected to the top of the spring groove through a spring. When the folding film 11 is blocked, the spring and the vibration block 31 are pressed downward. After the blocking is completed, when the driving plate 4 drives the rotating rod 10 upward, the spring and the vibration block 31 are reduced, and the spring drives the vibration block 31 to vibrate, shaking off the chalk dust on the outside of the folding film 11 into the collecting groove.

[0034] Working principle: The projector projects the blackboard for live broadcast, and the live broadcast account in the interactive platform reflects the situation in the live broadcast room, which is convenient for the teacher to understand the students' reactions in the live broadcast room during the live broadcast and interact with the students in time. The electric telescopic rod 3 moves outward, driving the moving rod and the interactive screen 1 to move outward. The interactive screen 1 moves to the outside of the driving slot 7 with the moving rod, which is convenient for the teacher to observe the situation in the live broadcast room while writing on the blackboard. During the outward movement of the interactive screen 1, the limit slot 12 moves outward, and the diameter of the rotating rod 10 in the limit slot 12 gradually increases, causing it to detach from the limit slot 12, so that the rotating rod 10 falls along the traction slope 13 when the interactive screen 1 moves outward, and the folding film 11 is unfolded to block dust.

[0035] When the electronic telescopic rod is retracted, the guide block 14 enters the guide groove 15, and the traction protrusion 16 drives the guide block 14 upward. At the same time, the electric telescopic rod 3 drives the moving rod and the interactive screen 1 to retract into the driving groove 7.

[0036] When the folding film 11 is blocked, the spring and the vibration block 31 are pressed downward. After the blocking is completed, when the driving plate 4 drives the rotating rod 10 upward, the spring and the vibration block 31 are reduced, and the spring drives the vibration block 31 to vibrate, shaking off the chalk dust on the outside of the folding film 11 into the collecting tank.

[0037] In summary, the live broadcast account in the interactive screen 1 is used to understand the students' reactions in the live broadcast room, which is convenient for interaction with students during teaching; the electric telescopic rod 3 is extended and retracted to drive the interactive screen 1 in and out of the driving slot 7 to control whether it is in use; the interactive screen 1 is moved outward to control the rotating rod 10 to fall from the traction slope 13, and the folding film 11 is unfolded to block dust.
